Resistor Overview

Resistor 2 banner cutout 770pxClaude Lyons produce an extensive range of high quality products to suit many applications.
Drawing on the long history from 1926 of the former British Electric Resistance Company ("BERCO®") the products of which became part of the Claude Lyons range in 1976, we pride ourselves on providing high quality resistors to a vast range of users including laboratories, industry and defence.

All Claude Lyons Berco® and Bercostat® resistive products are available with MOD and NATO codes to meet defence and maintenance requirements.

Bercostat® Rotary Rheostats - An extensive range of rotary rheostats to suit all industrial and laboratory needs comprising seven basic frame size models from 25 watts to 500 watts with ohmic values from 1Ω to 15kΩ. Available options include hand or motor driven, single or ganged, open or enclosed.

Berco® 'J' Coil Resistors - A helix of edge wound resistance strip, mounted on porcelain insulators which in turn are mounted on a steel support.  The maximum surface area of the resistance material is exposed to the cooling air to give the maximum dissipation of heat and thus the highest possible rating. Available in ratings from 0.1Ω - 5.08Ω. J-Coil-100px
Berco® Tubular Fixed & Sliding Resistors - Tubular resistors meet the demand for users requiring high dissipation capacities. Their robust construction readily lends them to many industrial and laboratory uses. Single and multiple tube models are available. Ratings from 240W - 1080W 0.2Ω - 1.4KΩ. Tubular-fixed-100px
